Re: Hiring D programmers (with cryptography and blockchain knowledge are preferred)
Thanks for the interesting idea. I decided to try something similar. (just for fun). Decentralized Social Network (DecNet): Is a conjunction of facebook, twitter and reddit. Clients: Can create their own profiles (private key, public key, address, profile file) and share them through the network. Pull other profiles by address. Writing posts, replies, open threads, vote, etc. Content like images, videos, etc. cannot be stored in the profile file but should be linked through special tags (like html?). Every client provide their own profile file. Servers: Will provide a list of addresses where profile files can be found including an address of the owner. Will backup profile files. 1. Content cannot be in blockchain because of overbloating the network. Every profile has their own `file` with all the content in it. 2. `Servers` can setup their exchanging limits. Like profile size limit (default 40 MB), time to live (3 to 48 hours from last profile pull). More info will be added to the README later. https://github.com/SatoshiR/DecNet People... It just came to mind... it's a very bad idea to make an incensurable social media. It would be a safe heaven for pedophiles, drug traffickers, human traffickers, > hitmen and criminals alike. It's similar to working as a programmer for a military. You are just a provider who provides the software.

Anyway, they don't have enough money to do that. Somebody needs to come in and foot the bill, otherwise this type of infrastructure code is all on peoples own time and desire.

I do not think the debate you have with yourself is decentralized vs centralized. You are thinking about moderated vs unmoderated. One is a technical structure, the other is a social one. We got used to have moderated channels in media and unmoderated channels in person. Now the problem we are facing is that we use these social media platforms for replacing "in person" communications with friend and family. And the owners of these platforms are still treating it as "media" that they should moderate. But this is not so black-and-white still. When i am talking to my mother-in-law who has different political biases than me, I moderate *myself* not to bring up topics that would just divide us, because I love her enough to tolerate her opinions. What happens is that we have many social circles in which we have different topics and ethical norms. This is in our nature and that is fine. Football fans ventilate their emotions at the game, but they would not use the same language in their workplace. So what I see is that a social media platform should be decentralized to avoid influence from its owner. It should be divided into many communities. And each community should be able to downvote content that is not tolerated in those circles. And downvoted content should be also available by others, it should just take more actions to peek into that and convince yourself that it was indeed something inapt for that community. In the digital world, everything seems to be black and white. But social behaviors are more subtle than that. It is easy to create a total dictatorial system like facebook, and it is also easy to create a total anarchist system like Silk Road. And our goal is to create a system that is similar to in-real-life communication, which is neither completely free, nor completely controlled. You cannot build that system on top of a centralized architecture where a government can just ask for all data including a order to keep that secret. People never trusted their inner thoughts or family conversation onto the government. And they should not. This answer is brilliant...it comes out of understanding...deep thinking Now...personally I don't think this social media platform potential hype will last. Very soon it will get out of hand. It means Facebook, etc. that doesn't offer any quantifiable needed value will die if they don't innovate out of the social media realm. Presure from governments and users needs will facilitate the death of the social media market. But one thing is certain. Security is becoming a problem. Monies are becoming digital. There is a rising need for securing digital value without sacrificing convenience. Our systems today are not designed for that. Sooner or later those patches we are making to our systems temporary will get exhusted. Its either an innovative use of blockchain-like systems or a secure-from-scratch sandboxing system. Blockchain seem interesting for D.

Nah, anyway decentralized != anonymous. Even in Tor there are
servers.
What we need isn't a decentralized http replacement. What we
need is a decentralized dns with some form of filters available.

1 = Vitor
2 = Vitor

(cents 1, 2, 3 belong to Vitor and cent 4 belong to Leonard, and
so on...). A "map" (C++) or associative array (D) with the ID of
the cent (key) and owner (value) or opposite, if necessary.
Is this even possible? Please consider that I don't know a lot
about cryptography. And I have no idea of whether this is
feasible with D or with any language at all, so if I'm speaking
nonsensic things, just tell me.
But I think it would be lighter than store all transactions from
the very first one.
I just don't know if this is doable; cryptocurrencies have a lot
of security measures to avoid transferring money that doesn't
exist, money that isn't yours, and so on, to confirm the
transaction...
Wouldn't it be easier? All the cents should have a first owner
though... one that would sell to resellers, or just give away to
random people.
That way, the blockchain would have a fixed size, forever.
Lighter than all that expensive mining stuff (that in my country
is impossible - lack of decent machines, pricey electric energy),
and the worst part: downloading 100+ GigaBytes because blockchain
stores transactions, this database gets bigger and bigger...
List of cents is limited; it's fixed. But instead of 18 Million
that bitcoin uses, I was thinking of trillions (so the value of
the currency is more aligned to fiat currencies that we already
know and are used to).
So... tell me. Is this possible? *Is this safe*? Is anybody going
to be stolen if blockchain stores a map of cent id + owner
instead of a bunch of transactions?
I know that it would be lighter for CPUs of users and servers as
well, and to the disk, that's for sure.
Waiting for replies.
